2002-11-12  Bill Haneman <[e-mail]>

	Fixes for bugzilla 95942 and 98236.

	* magnifier/magnifier-private.h:
	Added cursor_default_size member.

	* magnifier/magnifier.c:
	(magnifier_transform_cursor):
	Changed to resize with respect to cursor default size, 
	instead of cursor's *current* size. [98236]

	* magnifier/zoom-region.c:
	(zoom_region_queue_update):
	Add zoom_region_process_updates as an idle handler
	on receipt of an update to queue (rather than running the
	idle handler continuously).
	(zoom_region_update_pointer):
	Fixed to correctly detect when the zoom_region has been 
	destroyed, and return FALSE then.
	(zoom_region_update_pointer_idle):
	Changed to queue a timeout-based pointer query and return
	FALSE if the pointer has stopped moving, otherwise keep spinning the idle
	handler. [95942]
	(zoom_region_update_pointer_timeout):
	Reinstate this function and queue an idle handler if the pointer
	has moved since the last timeout, which spins until the pointer
	gets quiet.
	(zoom_region_init): Changed to queue a timeout rather than
	an idle handler for the pointer update.
	(zoom_region_finalize):
	Do useful freeing of memory instead of just doing nothing ;-)
	stops massive memory leakage if multiple zoomers are created/destroyed.

2002-10-24  Bill Haneman <[e-mail]>
 
	* acconfig.h: Added this missing file, with
	template for HAVE_XFT.

2002-10-22  Bill Haneman <[e-mail]>

	* magnifier/magnifier.h:
	Add a #define for the OAFIID string.
	Fixed type in the IS_MAGNIFIER() macro.

	* magnifier/magnifier.c:
	(magnifier_gobject_dipose):
	Create this method from impl_magnifier_dispose;
	Fix a race condition in magnifier destruction.
	Removed the unref() of the property bag, this happens
	automatically on object disposal because of the way property bag
	is declared (bonobo_property_bag_new_closure).
	(magnifier_class_init):
	Add the gobject dispose handler.

	* test/mag-test.c:
	(get_magnifier): Change so that varible "magnifier" is not
	shadowed, and to avoid the peculiar declaration of "static"
	variables within a method block.

	* magnifier/magnifier-main.c:
	(magnifier_main_pan_all) (magnifier_main_refresh_all)
	Added guards for the timeout methods, to make sure the object
	hasn't been disposed when the timeout is called.
	(main):
	Added calls to g_timeout_remove() for the timers.

2002-10-21  Bill Haneman <[e-mail]>

	(MagnifierOptions) (main): Add code to set cursor-color.
	
	* magnifier/magnifier.c:
	(magnifier_scale_cursor): renamed "magnifier_transform_cursor".
	Added code to recolor the magnifier cursor's "black" pixels, if
	a cursor color has been specified.
	(magnifier_recolor_pixbuf) : New method, to support cursor color.
	(magnifier_set_property) (magnifier_get_property) : Cursor-color
	fixes.

	(_get_x_cursors) : New method to grab X cursor set.
	(zoom_region_source_root) : Get the root source GdkWindow.
	(zoom_region_update_pointer) : Add code to check the
	current X cursor, using XTest.  Does not seem to work reliably,
	#defined out via TEST_XTST_CURSOR block.

	* cursors/1_32/*.xpm:
	* cursors/1_48/*.xpm:
	* cursors/1_64/*.xpm:

2002-10-18  Bill Haneman <[e-mail]>

	* magnifier/magnifier-main.c:

	struct member.
	
	* magnifier/magnifier.c:
	(magnifier_properties_init): 
	Fixed naming bug, "cursor-scale-factor" was incorrectly
	referred to as "cursor-mag-factor".
	
	* magnifier/zoom-region.c:
	Stifled some debug printfs.
	(magnifier_set_property) : Fixed bug when setting "smoothing-type"
	property to "none"; we now revert to NEAREST_NEIGHBOR
	interpolation.
	
	
2002-10-17  Bill Haneman <[e-mail]>

	* idl/GNOME_Magnifier.idl:
	Added struct Point (GNOME_Magnifier_Point).

	* magnifier/magnifier.c:
	(PropIdx): Added
	MAGNIFIER_CURSOR_COLOR_PROP,
	MAGNIFIER_CURSOR_HOTSPOT_PROP,
	MAGNIFIER_CURSOR_DEFAULT_SIZE_PROP,
	MAGNIFIER_CROSSWIRE_SIZE_PROP,
	MAGNIFIER_CROSSWIRE_CLIP_PROP,
	MAGNIFIER_CROSSWIRE_COLOR_PROP
	(magnifier_regions_refresh_cursor): Removed.
	(magnifier_scale_cursor): Changed to use new properties.
	(magnifier_init_cursor): Initial code for recoloring cursor
	pixmaps (non-functional).
	(magnifier_get_property) (magnifier_set_property)
	(magnifier_init): 
	Added support for new properties.
	(magnifier_set_pointer): Removed.

	* magnifier/magnifier-private.h 
	* magnifier/magnifier.h:

	(zoom_region_paint_cursor):
	(zoom_region_unpaint_cursor):
	(zoom_region_paint_crosswire):
	(zoom_region_unpaint_crosswire):
	Major changes to cursor drawing, to support new features.
	Crosswire now can draw XOR, colored lines/rects, and
	can be clipped by the cursor's rectanglar bounds if 
	desired.
	(zoom_region_update_cursor_pos):
	(zoom_region_update_cursor):
	(zoom_region_update_pointer):
	New functions for cursor tracking and updating.
	(zoom_region_update_pointer_idle): GIdleFunc for checking the
	pointer position.
	(zoom_region_moveto): update the pointer before scrolling.	
	
2002-10-16  Bill Haneman <[e-mail]>
	
	* magnifier/zoom-region.c:
	(zoom_region_update_pointer) (zoom_region_update_pointer_timeout) 
	(zoom_region_update_pointer_idle) : New methods, for making sure
	the displayed cursor position in the magnifier is current.
	(impl_zoom_region_dispose): call g_idle_remove_by_data more than
	once.
	(zoom_region_init) : Add the idle func for checking the mouse
	position.	
	(zoom_region_paint_*): Change the second GdkRectangle param to a
	pointer.
	(zoom_region_paint_cursor): Don't bother clipping if the second
	parameter is NULL.
	(zoom_region_paint_crosswire_cursor) (zoom_region_cursor_rect): 
	Don't use the magnifier->priv->cursor_x, etc. positions, 
	ask for the current mouse coords from GDK when painting the
	cursor.

	* magnifier/magnifier.c:
	(magnifier_set_cursor): Don't force refresh of the zoom regions
	anymore, they are now responsible for their own mouse coord finding.

	* magnifier/magnifier-main.c:
	(magnifier_main_pan_image): Revert the change from last night
	which forcibly updated the mouse coords; zoom regions are now
	responsible for doing this themselves.  
	(This is much more performant).
	
2002-10-15  Bill Haneman <[e-mail]>

	* magnifier/magnifier.h:
	(magnifier_set_pointer): New method.

	* magnifier/magnifier-main.c:
	(magnifier_main_pan_image): Changed to check the mouse and
	call magnifier_set_pointer() whenever it moves, even if "mouse
	tracking" is not on; this means that the zoom-regions accurately
	reflect the pointer position.  However latency is too big, this is
	a temporary fix and a more performant one is expected.

	* magnifier/magnifier.h:
	Added a gboolean "crosswire" member to the struct, to facilitate
	simultaneous crosswire+normal cursor.

	* magnifier/magnifier.c:
	(magnifier_set_pointer): New method.
	(magnifier_regions_refresh_cursor): New internal method (possibly
	temporary).
	(magnifier_get_cursor): Changes to support simultaneous crosswire
	and 'normal' cursors. (Not yet complete).

	* magnifier/zoom-region.c:
	(zoom_region_paint_cursor): Changes to draw a "normal" cursor only
	if there is a valid GdkDrawable for it in the magnifier private
	structs.  This prevents error messages being printed for
	cursor-set="none".
	
2002-10-15  Bill Haneman <[e-mail]>

	* magnifier/magnifier.c:
	(#include): added #include of <X11/Xatom.h>.
	(magnifier_realize): Set the WM_TYPE of the magnifier
	toplevel window to _WM_TYPE_DOCK; this will work OK until the
	Metacity RFE for a new WM type (for special, always-always-on-top
	windows) goes in.
	(magnifier_unref_zoom_region): Commented-out cast of user_data to
	"Magnifier" since we don't use it yet.
	
2002-10-14  Bill Haneman <[e-mail]>

	* test/control-client.c:
	New file, exercises a couple of simple pieces of control API for a
	running magnifier instance.

	* test/mag-test.c:
	New file; tests a new or running magnifier by clearing all zoom
	regions and creating four new ones with various parameter
	settings.  NOTE: If the pre-existing magnifier is tracking the mouse,
	the resulting test will, too.

	* idl/GNOME_Magnifier.idl:
	Renamed method "resize" to "moveResize".

	* magnifier/GNOME_Magnifier.server.in.in:
	Fixed brokenness in the .server file, in terms of 
	namespace and versioning.
	
	* magnifier/Makefile.am:
	Removed reference to removed file "mag_control.c".
	
	* magnifier/magnifier-main.c:	
	(magnifier_main
